Carpets, especially those in basements, can get wet and if this moisture is not removed by wet vacuuming or airing out the area, mold can develop. Letting mold remain in a carpet can cause health issues ranging from irritated eyes, nose, and throat to allergic reactions and lung issues. It is not easy to kill mold in carpeting but it can be done without using a professional or removing and reinstalling carpeting.
You will need:
Step 1: Mold is toxic and can be inhaled or come in contact with skin so protect the eyes, hands, and mouth with the goggles or glasses, gloves, and face mask, respectively.
Step 2: Conduct mold testing throughout the house to make sure that mold is not present in other locations. If it has reached other areas or gotten into the HVAC system, carpet cleaning alone will not be sufficient. Purchase a mold test kit that supports testing of multiple surfaces and another kit to test the HVAC system.
Step 3: Begin removing mold from carpet by renting a carpet cleaning machine and using the appropriate detergent and water to clean the fibers. If this does not remove the mold, fill a bucket of water with 1 cup of either bleach or ammonia (not both) and transfer some solution to a spray bottle. Spray the carpet and let the solution remain on for 15 to 20 minutes before removing it with the carpet cleaning machine. Remove as much water as possible from the carpeting because any moisture that remains could lead to additional mold.
Step 4: Open windows in the room and set up fans to blow on the carpeting to dry it. If a dehumidifier is available, shutting the door to the room and turning on this equipment will remove moisture more quickly. Once the carpet is completely dry, close the windows and remove the fans and dehumidifier.
